Sufficient observables for large scale structure in galaxy surveys
Julien Carron, Istvan Szapudi
Beyond the linear regime, the power spectrum and higher order moments of the matter field no longer capture all cosmological information encoded in density fluctuations. While non-…
On the Coherence of WMAP and Planck Temperature Maps
András Kovács, Julien Carron, István Szapudi
The recent data release of ESA's Planck mission together with earlier WMAP releases provide the first opportunity to compare high resolution full sky Cosmic Microwave Background te…
Optimal non-linear transformations for large scale structure statistics
Julien Carron, Istvan Szapudi
Recently, several studies proposed non-linear transformations, such as a logarithmic or Gaussianization transformation, as efficient tools to recapture information about the (Gauss…
Statistical ensembles of virialized halo matter density profiles
Julien Carron, Istvan Szapudi
We define and study statistical ensembles of matter density profiles describing spherically symmetric, virialized dark matter haloes of finite extent with a given mass and total gr…
